Primary Production and Species Richness in Lake Communities 1997 - 2000

An understanding of the relationship between species richness and productivity is crucial to understanding biodiversity in lakes. We investigated the relationship between the primary productivity of lake ecosystems and the number of species for lacustrine phytoplankton, rotifers, cladocerans, copepods, macrophytes, and fish. Our study includes two parts: (1) a survey of 33 well-studied lakes for which data on six major taxonomic groups were available; and (2) a comparison of the effects of short- and long-term whole-lake nutrient addition on primary productivity and planktonic species richness Dodson, Stanley I., Shelley E. Arnott, and Kathryn L. Cottingham. 2000. The relationship in lake communities between primary productivity and species richness. Ecology 81:2662-79. Number of sites: 33理解物种丰富度与初级生产力之间的关联，是解析湖泊生物多样性的核心要点。本研究围绕湖泊生态系统初级生产力，与湖泊浮游植物、轮虫、枝角类、桡足类、大型水生植物及鱼类的物种数量之间的关系展开系统调研。本研究包含两部分内容：（1）对33个已被充分研究的湖泊开展调查，上述湖泊均具备六大主要分类类群的相关数据；（2）对比短期与长期全湖营养添加实验对初级生产力及浮游生物物种丰富度的影响。本研究引用文献：Dodson, Stanley I.、Shelley E.
